As for the Dinan, they only claim about 6 hp and I think I'm getting way less. I would only recommend it for the increased rpm and removal of the speed governor. Since I autocross and have a 4.10 final drive, that was worthwhile for me. I think there are other chips that can give you returns in the mid-teens (claimed 30 hp, but I don't believe it). You may have a slight worry about your warranty, which is not an issue.
Don't forget, at sea level, 100-octane gasoline is good for around 30-hp. At between seven and eight dollars per gallon, that's real cheap hp. At altitude the octane works against me, but at sea level, a filter and a tank of gas gives you almost 10% rear wheel hp increase. Add a final drive on top of that and your adding hp and torque significantly.

Thanks again for even more information.
If there are other vendors out there that have better gains, why did you decide to stick with Dinan since the gains seem to be minimal? You might be able to extract more power from other software combined with your 4.10 final drive. Was warranty a concern of yours? I am concerned about warranty and want to keep mine in place as long as possible that is why the Dinan route seems the best for those of us who want some kind of warranty with mods to our cars. I had a lot of Dinan products on my old M3 and was quite happy with them. Just getting the MS filter from EAS sounds tempting right now...
Did you notice any adverse affects to your gas mileage with the 4.10 final drive? I don't autocross so would the Dinan 4.10 final drive be fine for a street driven car? Thanks.
